Had a good time staying at Kasamsan's place. It was very clean (especially the toilets and sink) and had all the basic amenities needed for the stay.
Location is slightly far from the BTS (about 15 to 20mins walk to Ekkamai Station). Taking a taxi is fine but be prepared to spend more time during peak hours.
All in all it is an amazing place to stay and very value for its price considering what it provides. Looking forward to my next stay at Kasamsan's place!
